Abstract

In this study, a Yanggaeng with added loquat fruits puree was developed and studied on quality characteristics. The mixed ratio were 0%, 20%, 40%, 60%, 80%, 100% of loquat fruits puree. Loquat fruits puree have 83.49% of water, 0.36% of crude protein, 0.04% of crude fat, 0.46% of crude ash, $14.3^{\circ}Brix$ of sweetness, 75.10(mg/kg) of polyphenol and 4.01 of pH. The water contents of Yanggaeng were 41.78~53.37%, and showed significant increase (p<0.001). The sugar contents of Yanggaeng were increased from $28.7^{\circ}Brix$ at control group to $36.0^{\circ}Brix$ at 100% mixing group (p<0.001), while pH were decreased from 6.4 at control group to 4.26 to 6.4 at 100% mixing group. In color, the brightness (L-value) gradually decreased from 72.69 at control group to 43.64 at 100% mixing group (p<0.001), the redness (a-value) of control group was the lowest by -1.72 while 100% mixing group was the highest by 8.64 (p<0.001). The yellowness (b-value) of control group was 15.91 while that of 100% mixing group was 21.98 (p<0.001). The DPPH radical scavenging activity of control group was the lowest by 9.24% while that of the group 100% mixing was the highest by 46.17%. Total polyphenol was not detected from control group and 20% mixing groups, and 100% mixing group was The highest by 16.69 mg/100 g (p<0.001). Preference test showed the groups with mixing loquat fruits puree 60% or more were preferred (p<0.001) in color. There were no significant difference from sweet taste but sour taste of 100% mixing group was The highest by 4.85 (p<0.01). For texture and overall preference the most preferred groups were the groups of mixing of 60% and 80% of loquat fruits puree.

본 연구는 비파를 이용한 양갱의 최적 배합 비율과 비파 퓨레와 비파양갱의 이화학적 품질특성을 조사하였다. 그 결과, 비파 퓨레의 첨가량이 증가할수록 수분, 당도, pH, 항산화 활성 및 폴레페놀 함량이 증가하였고, 관능적 품질 특성에서는 비파 퓨레 60~80% 첨가시에 선호도가 높았다. 따라서 비파양갱의 최적 배합비율은 비파 퓨레를 60% 첨가시 맛과 기호도에서도 좋으며, 다양한 기능성이 기대되는 양갱을 만들 수 있을 것으로 기대된다.
